ACROSSは線形力学系の優れた評価・計測法である。地下の構造と状態の能動的監視観測の質的レベルを上げるには、ACROSSの手法に加えて安定で信頼のおける地震計の稠密アレイが必要だ。それには、信頼性が高い安定で安価な地震計を確保しなければならない。このような現実的な問題に対する解決の道を、地震計のアクロスによる校正法が与える。

Focusing on the cover layer materials (as the Radon Barrier Materials), which could have the effect to restrain the radon from scattering into the air and the effect of the radiation shielding, we produced the radon barrier materials with crude bentonite on an experimental basis, using the rotary type comprehensive unit for grinding and mixing, through which we carried out the evaluation of the characteristics thereof.
